4.31.8.9.7 Temperature measurement - Configuration
The temperature measurement channels can be configured independently of each other. All the registers required
for each channel are arranged separately.
The "SensorType" register needs to be adjusted in order to enable a temperature channel. The rest of the registers
complement this configuration and only need to be defined as required.
4.31.8.9.7.1 SensorType
Designations (pChannelName):
Cfo_SensorType01
Cfo_SensorType[02...06]
The "SensorType" registers control the basic functionality of a temperature channel.
